Hi Chris,<br>
<br>
for the switches ports stuff check out this url:<br>

<br>
We have finally configured an internal (private) VLAN joining there one
NIC of each blade server. Now all cluster related traffic goes through
those interfaces (eth2 at both servers in our case), including the
traffic generated by the lock_dlm of the GFS2 filesystem, just created.
<br>
<br>
To check multicast connectivity, these are two very useful commands,
"nc -u -vvn -z <multicast_IP> 5405" to generate some multicast
udp traffic and "tcpdump -i eth2 ether multicast" to check it from the
other node. (eth2 in my particular case, of course).<br>
<br>
I have been playing a little with the lock_dlm, but here is how my
cluster.conf looks now:<br>
<br>
<small><font face="Courier New, Courier, monospace"><?xml
version="1.0"?><br>
<cluster config_version="7" name="VCluster"><br>
<fence_daemon post_fail_delay="0" post_join_delay="25"/><br>

</fencedevices><br>
<rm><br>
<failoverdomains/><br>
<resources/><br>
</rm><br>
<dlm plock_ownership="1" plock_rate_limit="500"/><br>
<gfs_controld plock_rate_limit="500"/><br>
</cluster></font></small><br>
<br>
Next thing to add... I'm going to play a little with the quorum devices.<br>
<br>
Hope it helps!<br>
